Brave Halfling Publishing produces inexpensive supplements for what is sometimes referred to as old school or original edition roleplaying, including Labyrinth Lord and OSRIC. These two games, though, are actually OGL-enabled emulations of early editions of Dungeons & Dragons. So to give your 1970s style game a little taste of the new millenium, Brave Halfling has just released Delving Deeper, a PDF with three alternate skill systems—d6 skills, Attribute Skills, and Percentage Skills. It’s only 75¢. And for free, the company is offering The Halfling Adventurer, four pages of options for taking Halfling characters beyond the fourth level.
